IRULE to search Certificate Subject and Set Username.

Good Afternoon,

I'm trying to get an IRULE to use the Client SSL profile Request handshake to filter the cert and subject. IRULE was crafted-reused from a few other DevCentral Post.

Here's where I'm at: Error 4: error: ["unexpected end of arguments;expected argument spec:CERTIFICATE"][X509::subject]

when CLIENTSSL_CLIENTCERT {

  if {([SSL::cert 0] eq "") or (![X509::subject] contains "irene")} {

   Reset the connection
    reject

} else {

set subject_all [X509::subject [SSL::cert 0]] log "Subject: $subject_all" binary scan [md5 $subject_all] H* user_hash log "$user_hash" } }

What am I missing?

Cheers!
